EIGRP is a Cisco proprietary protocol. If you don’t mind being locked in using a vendor specific protocol you will then enjoy using a robust, well-developed protocol that will meet most enterprise network needs. Here are a few basic bullet points about EIGPR:
Configuring a basic EIGRP network:
Network Design (I’m using sub-interfaces on my equipment, as I have other traffic on other sub-interfaces):
Step 1) Enable EIGRP on every router:
Recently I was thinking if there were any tools available for me to enable some continuous ICMP packets to ping a remote router for reachability. Found a nice tool within Cisco’s IOS that gets the job done. IP SLA has many options, but the one I will be discussing here is a simple ICMP-ECHO message what will just ping a remote router to check for reachability.
So you have been tasked with drawing a network diagram, and you run to the typical first option (pen + paper). This works for some situations but not all, especially when you need to have a nicely presented diagram.
I have been looking for software that is cheap that could replace Visio for me and I think I found what I was looking for. draw.io is an incredible tool which allows you to draw networks, save your templates, and print for distribution all for the price of $free. I know its hard to believe but you should check it out and let me know if this tool has worked to replace your (pen + paper), Visio, or other network drawing tools:
Its been a decade now since the original iPhone came out. With so much progress with technology and smartphones in general, our expectations seem to grow more and more. With the announcement of the new iPhone X (X being the roman numeral symbol for “10”) many, including me, expected a phone that would shape the next decade and live up to the standard of a device which truly can be called “One More thing….” Did we get that phone? No, I don’t believe so. Here are my 5 reason why I don’t believe iPhone X will be shaping the future of smart phones:
CCNP Routing & Switching ROUTE 300-101 Chapters 3 & 4 Notes:
- IPv6 Address breakdown
- 32 hexadecimal numbers
- 8 quartets
- 4 hex digits separated by a colon
- 128-bit IPv6 address
With the depletion of IPv4 addresses IPv6 was created to solve that problem.
